Peter Jackson gets 'killer' into NZ

A man convicted in the United States of murdering three 8-year-old boys has been allowed into New Zealand - after film-maker Sir Peter Jackson approached Immigration on his behalf.

Damien Echols served 18 years in jail and was on death row until he was released from an Arkansas jail in August after he and two others agreed to change their pleas to guilty.

New tests in 2007 from the crime scene proved negative for the trio's DNA and showed others were present when the three Cub Scouts were murdered.

The controversial case divided the state of Arkansas and attracted the attention of a number of celebrities, including Sir Peter, who were drawn to the case after a documentary suggested the men were innocent.

The Herald understands Mr Echols has been in the country for at least a week as a guest of Sir Peter.

It is understood the Oscar-winning director approached immigration officials himself to ask if Mr Echols could be allowed in for a short period as his guest.

Because his murder convictions still stand, he needed a special direction - a form of character waiver - from Immigration NZ or its associate minister to be allowed entry.

Normally, anyone convicted of murder would be considered an excluded person under section 15 of the Immigration Act 2009.

Sir Peter's approach is believed to have been the catalyst for Mr Echols' visa being granted.

There has been speculation in United States media that Mr Echols has been given a small role in The Hobbit, which is in production in Wellington.

However, it is believed he has not been issued with a work visa so is not legally allowed to work while here.

Despite the guilty pleas of Mr Echols and his co-accused, the state allowed them to maintain their innocence while recognising prosecutors probably had enough evidence for conviction.

They also had to give up their right to seek compensation for a miscarriage of justice.

They were convicted in 1994 of killing Cub Scouts Steve Branch, Christopher Byers and Michael Moore, whose bodies were found in a West Memphis ditch naked, bound and mutilated.

Last year, Sir Peter denied he was making a film about the West Memphis Three. But a source said he was possibly considering making a documentary about the case and that was the reason for Mr Echols' visit.
